To all whom. t may concern:

Bo it known that I, Camus GlLnenr Hwunemcitigrn' of he United ftel, r sv mglet `,n1tecountyo an 5 Siete ofillinois, have invented e' certain new, useful, and Im roved Flexible Fluid-Joint, ofwhich the fol owing is e. full, clear, and exet deecripton', auch se wiii enbie others skllednx the ort to which it appertaine to :e make end us'e the saine. L..

M lnventon relates v ,liexible joints for ui Apipes or condxiits; and the object of the invention is to provide asixnple, eilective, and durable flexible joint for connecting the ends z5 of various lioidyipes or, conduits.

A further object of my invention is to im prove the form and construction of bell- 'ointe for fluid-pipes. It is usual to 'jointe of this enerel clase with 11:' g that 1 tre oorniposer of herd non-metallic com pounds',y ich as hard rubber. These gaskets are ve expensive; andthe ortie Yohieet of'this invention is to provi e s llexible joint in which a softpeeking may b e employed in z5 place of the common gasketfringe;

with this objeetin view my invention oonests, primarily, in e rotery or exble Yor 'hellfanl-.Gkbt joint the socket member of which ie provided with en grows to aofrwziy; .suitable 'Paclne ma 5 in MP* binetion with e suitable preferehiy metaihe, bend or atrapar-ranged in sandV groove an eutehie meule for exerting tension upon seid bend or strap toele ortilgen the pack.- 3 5 the contained mem ofthe joint 0r wup. M My invention consists, pertienlerly, il; e novel ball-end-socket joint comprising a. il member. in combination wi a socket memo ber metelic socket-surfaces between which sai ball member is confined, said socket member also having en 'mternel p'e; ripheral groove to contain materiel., a mete! and 'arranged wit the eovefto the pac-ki and rese te same egeinst the hellmem er, an moonen on the exterior of said et .member for tn wng out the end of seid bendto tighten said pecl:- ing and further my invention consists In vemgendeteils wnstmeton and in eem binatens of erts, all as hereinafter described, end partial-)arly pointed the claims. The inw-mien win t me .unafrgmwl by relemmte the -eceompenying provide d A'or socket-surfaces 4 and 5 to l drical openmg or recess fied form of the strep or bend u vice which I me?v employ.

It will be understood from the followin description that my invention is ca'peble o edeptsligxiis tg rotary vmrd d f many utitispartwnlnrl' evxsed or embodiment in ball-end-sockngjointeend is thus illuetreted'n the drawings. I

In my invention I provide a socket mem-..- ber2endebll memher.' members are provided with' sbonk! in the usuel manner and omhollow to form-i; 111mlA conduit; The here nely nr ished or ground bxli-eurfwe, and the' Boeket member is rovided withtwo eolrets 8 iatterrbeing hxrnisfled bythe bell, the lug 6 which is screwed into the outer of t e et mem- .herv propel-2. The socket member is proviifdhwiih m inermi @mismas-ij .9 en t e 6 is engt ci ma.' p ug within the sooket member. In this manner .I form en annular' or n'pherel packing-groove .8 within ,thev` aoc et member and surrounding' the ball 95 member between thel metal eocketl-suriaces VIt 5. In the side of the soeketmemher I provide a slot or opening 9. This le preferably formed upon s. tangent to the internal v fall of the socket member, thenajly providing sharp edge or corner 10. lthxn the pecl;- in Jove 8 is e band orstrep 11,.preferehly of the full width of the groove 8. and 1l is referablv of metal end one end l'orme into e hook tlf, which is ep the Shar edge or comer l0. The ot er end 1l" of t e strap or bend pulce out throu the hole 9 and is attached to winding-pin l2 emiro@l )eine of 75 Beth ef 'these se lied to lo;

on the exterior of the socket member. This winding-pin may be arranged between lugs I3 and is provided with spolygonal end l2 und s. nut 12, by which rt muy he secured oftor it is adjusted. By turning the pin 12 the band may be closed ortightcned around the ball to compress the soft packing or other material 14', with which the cove 8 is filled.

l prefer that the hooked endg-ll of the barril ic shell have along hook-point 11 tolep across the hole 9 in 4the socket member to prevent the loss of the aching through said opening.

To render the and automatic in operation,

it may be mede of springsteolfand corru- 15 gated, es shown in Fig. 2, so that when once placed under tension by means of the tension-pin 124 it will thereafter automatically take up the weer or slack of the aoking.

my flexible joint the band In assembl :o is lmt edjns within the socket member. The ball is then laced in the socket and the eprice. between t e ball and the bend is filled with he socket-plug 6 is then screwed home to comprese the pac and a 5 secure the ball in place, after which thepackis further compressed b contracting the pac band by means of t e tension device 12 11s.l Q ve descri iro: some uses of my flexible joint the ro- 3o jecting tension device 12 isi ein] an jectionabldend in suchcases pre er to substitute therefor the take-up or tension device illustrated in Fig. 3. In this instance the side of the socket member 2 is rovded with a number of teeth 15, and the ce end of the stx-:E r band 1l liasa'hookll t-o eng e the tee The strap is also provided with a tongue l1"`to receive the point of a. tool 16, biy'which the strap may be readil tightened. 4o I desired, n tool-lrole may be Kleed in the strap back of the hook 1l', in w 'ch oase the tongue 1 l'msy be dispensed with. g An automatic take-up or tension device of much merit is illustrated inFigs. 4, 5 and 6 of the drawings. l When employing t 's de- I prefer to provide the socket member 2 with t epartial peripheral flanges 17 17, thereby forming a oove 18 on the side of the socket member. e tension device com- 5o prises.

Considerab eforce is the spring under tension readily dono in the shop where the joints are manufactured or even when the joints are in use, and when the s ring has co tension upon the' pao -band to constantly compress the soft packing against he ball member of the joint.

As it is obvious that numerous modifioabeen secured. o on the lug 17' it is obvious that it will exert a.
